将所有特殊字符移动到字符串的末尾
原文:https://www . geesforgeks . org/move-all-special-char-to-the-end-the-string/
在本文中，我们将学习如何将所有特殊字符移动到字符串的末尾。 例:
输入:！@$%^ & AJAY 输出: AJAY！@$%^ & * 输入:极客 sf！@ orgeek @ s a # $ c%o^mputer s * * science p # o @ rtal fo @ r ge % eks 输出:geeks forgeek 是一个面向极客的计算机科学门户网站！@@#$%^***#@@%
先决条件:Java 中的正则表达式 思想是遍历输入字符串并维护两个字符串，一个字符串包含普通字符(A，A，1，' '等)，另一个字符串维护特殊字符(@，$，等)。最后，连接两个字符串并返回。 这里是执行上述方法的
C++
// C++ program move all special char to the end of the string
#include <bits/stdc++.h>
using namespace std;
// Function return a string with all special
// chars to the end
string moveAllSC(string str)
{
// Take length of string
int len = str.length();
// traverse string
string res1 = "", res2 = "";
for (int i = 0; i < len; i++)
{
char c = str.at(i);
// check char at index i is a special char
if (isalnum(c) || c == ' ')
res1 += c;
else
res2 += c;
}
return res1 + res2;
}
// Driver code
int main()
{
string str1("Geeksf!@orgeek@s A#$ c%o^mputer");
string str2(" s****cience p#o@rtal fo@r ge%eks");
string str = str1 + str2;
cout << moveAllSC(str) << endl;
return 0;
}

Java 语言(一种计算机语言，尤用于创建网站)
// Java program move all special char to the end of the string
class GFG1 {
// Function return a string with all special
// chars to the end
static String moveAllSC(String str)
{
// Take length of string
int len = str.length();
// regular expression for check char is special
// or not.
String regx = "[a-zA-Z0-9\\s+]";
// traverse string
String res1 = "", res2 = "";
for (int i = 0; i < len; i++) {
char c = str.charAt(i);
// check char at index i is a special char
if (String.valueOf(c).matches(regx))
res1 = res1 + c;
else
res2 = res2 + c;
}
return res1 + res2;
}
public static void main(String args[])
{
String str = "Geeksf!@orgeek@s A#$ c%o^mputer"
+ " s****cience p#o@rtal fo@r ge%eks";
System.out.println(moveAllSC(str));
}
}
Python 3
# Python3 program move all special char
# to the end of the string
# Function return a string with all
# special chars to the end
def moveAllSC(string):
# Take length of string
length = len(string)
# Traverse string
res1, res2 = "", ""
for i in range(0, length):
c = string[i]
# check char at index i is a special char
if c.isalnum() or c == " ":
res1 = res1 + c
else:
res2 = res2 + c
return res1 + res2
# Driver Code
if __name__ == "__main__":
string = "Geeksf!@orgeek@s A#$ c%o^mputer" \
+" s****cience p#o@rtal fo@r ge%eks"
print(moveAllSC(string))
